The Process
How the PNOE Breath Test Works
Indirect calorimetry is the gold standard for measuring metabolism. You breathe into a precision mask connected to the PNOE analyzer — it measures oxygen you consume and carbon dioxide you produce, breath by breath, in real time.
01
Arrive & Prepare
For resting tests, fast for 4–6 hours and avoid caffeine beforehand. For VO₂ Max testing, come in comfortable workout clothes prepared for a graded exercise stress test. Our team will walk you through everything.
02
Put on the Mask
A medical-grade silicone mask forms a precise seal over your nose and mouth, connected to the PNOE analyzer. For resting tests, you simply lie back and breathe normally for approximately 10 minutes.
03
The Test
The PNOE captures breath-by-breath oxygen and CO₂ data. The active VO₂ Max test pairs the breath analyzer with a cardiac stress test — progressive exercise on a treadmill or bike with continuous heart monitoring — until maximum effort is reached.
04
Your Results
Your 23-biomarker report is reviewed and interpreted by Dr. Di Pietro, who translates the data into a personalized nutrition, exercise, and cardiometabolic strategy tailored to your goals.
Testing Options
Two Tests. Complete Metabolic Picture.
Please note: PNOE metabolic testing is a standalone diagnostic service and is separate from a preventive cardiology consultation or office visit. If you are interested in a comprehensive cardiology evaluation with Dr. Di Pietro, please inquire about scheduling a consultation in addition to your metabolic test.
Resting Test
Resting Metabolic Rate (RMR)
$250
Most calorie estimates are guesses — built on population formulas that can be off by 20% or more. The PNOE measures exactly how many calories your body burns at rest, and what fuel it’s using to do it. It’s the difference between a plan built on averages and one built on your actual physiology.

Active Test
VO₂ Max & Cardiometabolic Fitness
$350
VO₂ Max is the most powerful independent predictor of cardiovascular mortality — stronger than blood pressure, cholesterol, or smoking status. Knowing yours isn’t just for athletes. It’s essential preventive cardiology.
Includes a cardiac stress test — continuous ECG heart monitoring throughout graded exercise, performed under physician supervision.

What We Measure
Key Biomarkers Your Report Includes
The PNOE analyzes how oxygen flows through your lungs, heart, and cells — producing actionable data on each system’s contribution to your metabolic health and longevity.
VO₂ Max
Aerobic Capacity
The maximum rate at which your body can use oxygen during exercise. The single strongest predictor of cardiovascular mortality and a key marker of biological age.
Fat-Max
Peak Fat Oxidation
The exercise intensity at which your body burns fat at its highest rate — a critical target for weight loss, metabolic flexibility, and endurance performance.
RMR
Resting Metabolic Rate
The exact number of calories your body burns at rest. Essential for building nutrition plans that actually match your physiology, not population averages.
VT1 / VT2
Ventilatory Thresholds
The intensity at which your breathing pattern shifts — defining your true Zone 2 ceiling and anaerobic threshold for precision training zone prescription.
RER
Respiratory Exchange Ratio
The ratio of CO₂ produced to O₂ consumed, revealing whether your body is burning fat or carbohydrates — and how metabolically flexible you are.
Bio Age
Metabolic Biological Age
A composite assessment of your metabolic and cardiovascular function compared to age and sex norms — an objective benchmark for tracking longevity interventions over time.
Ideal Candidates
Who Benefits from Metabolic Testing?
Weight Loss & GLP-1 Patients
If you’re on semaglutide or tirzepatide, or struggling with a stalled metabolism, RMR testing reveals whether adaptive thermogenesis has slowed your burn — and how to correct it without sacrificing muscle.
Endurance Athletes & Performers
Runners, cyclists, and triathletes receive precision heart rate zone prescriptions derived from their actual ventilatory thresholds — not wrist-based estimates — enabling smarter, more effective training.
Longevity & Preventive Cardiology
VO₂ Max is among the most powerful predictors of how long — and how well — you’ll live. Annual testing establishes your baseline, tracks improvement, and validates that your prevention program is working.
Hormone & Metabolic Health Patients
Thyroid dysfunction, hormonal shifts, and aging can profoundly alter metabolic rate and fat utilization. PNOE testing quantifies exactly what’s changed — providing objective data to guide hormonal optimization and nutrition.

“A VO₂ Max number from a gym is interesting. A VO₂ Max number interpreted by a cardiologist — in the context of your lipids, your coronary calcium score, your blood pressure, your family history — is a clinical tool. That’s the difference between a data point and a plan.”

FREQUENTLY ASKED QUESTIONS
Dr. Di Pietro is always very helpful and will go out of her way to make sure I get the care needed. She is always accessible by phone should I have any questions, and she will follow up with me personally to make sure I am recovering well. Their office is very comfortable and has a home like feel. Much better than the normal doctor's office atmosphere. By far, the best doctor I have ever had!
Dr. Di Pietro has not only been a great physician for me, but also to my parents. My father had not seen a physician in over 30 years, and Dr. T made him feel at ease and calmly and comfortably walked him through everything he needed done. She has gone above and beyond many times for my family both in the office and in the hospital. Thank you!
Dr. Tiffany is a wonderful doctor full of positive energy and extremely warm hearted. Truly a blessing, I recommend her without any reservation.
This was my first visit to Dr. Di Pietro. I was greeted immediately and warmly. I found the Dr and her staff to be very helpful and friendly. I would have no hesitations in recommending Dr. Di Pietro.
I highly recommend this doctor. Her nurse/ receptionist was very polite and accomodating. Very welcoming and comfortable office. Dr. Tiffany made the visit very comfortable she has a beautiful personality that makes her bedside manner excellent. She doesn't leave until you have had all questions or concerns answered- you don't feel as though you're "just another patient" she makes you feel that she cares about people, something that sadly not all doctors share. I would recommend her to all my friends and family.
First time seeing Doctor Di Pietro, very informative and addressed my concerns. Followed up with me days after my visit to see how I was doing. Facility is clean and Dr. Di Pietro shows interest and care for her patients.
Dr. T rocks! She's a great Dr. and normal person. She's real, she's fun, and I love going to her office.
Love it here! First time I ever left a doctors office happy and optimistic! She listened to everything and went through each part and explained it and decided on a plan of care. She truly cares what happens to her patients and wants to help them. I left with a clear plan, steps to take on the road to getting better. I see her again in two months and i am looking forward to it! DEFINITELY RECOMMEND!
I feel very fortunate to have found Dr. Di Pietro since I moved here 2 months ago. She provides helpful information in an honest, and straightforward manner. She genuinely cares about you and your health. I feel doctor's like this don't happen often.
I have arrived at both my visits early and was taken within 5-10 minutes ! Dr. Di Pietro explained the results of my tests so that I had a clear understanding of them. I felt she listened to what I had to say, it was a collaborative decision on my treatment.
She found a problem that may have saved my life. She is outstanding!
Excellent doctor. Crisp, fresh and practical approach to health care---medical needs. The office staff--Karina is fantastic and insures an effective and efficient exchange with the insurance company/financial side of the visit.
